Abstract

The invention discloses a quenching agent for surface treatment of a shearing section of a lead pig cold granulator. The quenching agent is composed of polyalkylene glycol, dimethyl sulfoxide, polyvinyl alcohol, boric acid, copper sulfate, carboxymethylcellulose, nanometer titania, sodium laurylsulfate, potassium nitrate, potassium sorbite and water. The quenching agent obviously improves the quenching speed under the condition that it is ensured that embrittlement cracking cannot appear in a product, the duration of the quenching technology is shortened by 15% to 20%, meanwhile, the quenching agent has the good antibiosis, anticorrosion and aging-resistance properties, after multi-time use, the good property can be still kept, and the service life is long.

Description

technical field [0001] The invention relates to a quenching agent, in particular to a quenching agent for surface treatment of lead ingot cold granulator shear slices. Background technique [0002] Lead ingot cold granulator is the most advanced product on the lead-acid battery production line. The active power of the equipment all adopts the hydraulic system, the operation process is simple and convenient, the operation condition is stable and good, and it has the functions of environmental protection, energy saving, consumption reduction and efficiency increase. Since it was put into use in the market, the social and economic benefits have been remarkable, and it has won unanimous praise from the industry. The operation is balanced and reliable, without noise. The lead ingot is conveyed by the scraper to the slicer, and the lead ingot is cut into lead sheets with a specified thickness through the cutting of the slice, and then processed in a process. Among them, the slic...
